On May 10, The Daily Show host and all around mensch Jon Stewart ended the show with a plug for Planet Tad (by MAD writer and head-writer of The Daily ShowTim Carvell)! The book is on sale now — so any of you who were waiting for an official endorsement from Stewart before deciding to buy it, you’re all out of excuses!

In the video below, writer Tim Carvell talks about his new Planet Tad book, based on the blog parody featured in every issue of MAD. The book will be on sale May 8, and you can preorder your copy by clicking here!

Tim Carvell is a very funny fellow. Not only does he write MAD’s ongoing feature, Planet Tad, (soon to be a major book from Harper Collins) but he also has a day job as head writer for The Daily Show. Last night at the 2011 Prime Time Emmy Awards our boy Tim was on full display accepting the Emmy for Best Writing for a Variety, Music or Comedy Series.
